2. Flick the latch open with the thumb tip, and allow
the forward facing handle to drop away. Straighten out the fingers to let
the handle clear. Use thumb pressure to hold the handle securely against the
upper palm.

4. As the handle reaches bottom,
dip the wrist forward and down to help the handle over the top, while changing

5. Clearing the thumb might take

This move is a little
bit more difficult than the forward version. The hard part being the transition
form Thumb pressure grip to Knuckle pinch grip. The Thumb is much more
difficult to clear out of the way than the fingers. Keep at it, eventually
it'll come.

To test yourself, see how many
times you can execute the technique in a minute....... not an easy
task!
